Cells and formulas
Read the grid, write your first formulas.
Key ideas
Every cell has an address
C4Column letter first, then row number. C4 is column C, row 4.
Formulas start with =
=B2*C2Without the =, Excel stores your text as plain words instead of calculating.
Math follows the usual order
=2+3*4Multiplication and division happen before addition and subtraction. Use parentheses to change the order.
